P: Correct Lens Profile for Canon EF 11-24 F4L

Using an R6III with en EF 11-24 F4L via an EF to RF adapter, and I am noticing significant barrel distortion at the wide end that the profile in Adobe Camera Raw isn’t taking out.

The strange thing is that I used the exact same lens and adapter on my R6 mark 1, using the same lens profile in ACR and it corrects the distortion well.

Anyone have any insights?

I can correct manually but it gets tedious (shooting real estate)

    Is it possible for you to supply us with an R6III file that exhibits the issue?
